I'm sorry if this has already been posted before, i did do a search. From reading the forums it seems that some iphones have some defects with them and need to be taken back. Before I buy one, i wanted to have a list of the common defects so I can check my iphone at the store to make sure that mine is perfect . I believe this list will be useful to others as well. From reading the forums, here are the ones that I found. If you know of one that is not in this list, post it and I'll add it to this post. thanks.
